What are some common methods for tracking and displaying the number of visitors on a PHP website without using frames?

One common method for tracking and displaying the number of visitors on a PHP website without using frames is to use session variables to keep track of unique visitors. By incrementing a counter in the session when a new visitor accesses the website, you can accurately track the number of visitors in real-time. You can then display this count on your website by retrieving the value stored in the session variable. 

<?php
session_start();

if (!isset($_SESSION['visitors'])) {
    $_SESSION['visitors'] = 1;
} else {
    $_SESSION['visitors']++;
}

echo "Number of visitors: " . $_SESSION['visitors'];
?>
